Summary
Recurrent cardiac pseudoaneurysms caused by Teflon felt strip infection were successfully treated by removing the foreign material and using an omental graft for reinforcement.
Area of Science:
- Cardiovascular Surgery
- Infectious Diseases
- Biomaterials Science
Background:
- Teflon felt strips are used to reinforce cardiac suture lines after ventricular aneurysmectomy.
- Infection of these synthetic materials can lead to serious complications such as pseudoaneurysm formation.
- Multifilamented synthetic materials may harbor pathogens, increasing infection risk.
Purpose of the Study:
- To report a case of recurrent pseudoaneurysm secondary to infected Teflon felt strips.
- To describe a successful surgical strategy for managing this complex complication.
Main Methods:
- The patient underwent ventricular aneurysmectomy reinforced with Teflon felt strips.
- Multiple recurrences of pseudoaneurysm were observed, attributed to suture line infection.
- Surgical intervention involved complete removal of residual foreign material (Teflon strips).
- The cardiac suture line was reinforced using an omental pedicle graft.
Main Results:
- The patient experienced multiple pseudoaneurysm recurrences post-initial surgery.
- Infection was confirmed, originating from the multifilamented Teflon strips.
- Complete foreign material removal and omental graft reinforcement led to successful treatment.
- No further pseudoaneurysm recurrence was reported after the revision surgery.
Conclusions:
- Infected Teflon felt strips can cause recurrent cardiac pseudoaneurysms.
- Complete removal of infected synthetic material is crucial for successful management.
- Omental pedicle grafts offer a viable alternative for reinforcing cardiac suture lines in infected fields.
